Update.

Got my car back. New (used) engine, new CCV valve and hoses, new DISA valve, new VCG, Oil pan gasket, OFHG, oil filter, secondary air pump hose, lower radiator hose, and freon recharge. Car idles silently and pulls amazingly hard and smoothly.

Interestingly enough, the mechanic wasn't very happy about my catch can setup--according to him, it was installed incorrectly (needed to pass through the CCV and not into the intake manifold). He also stated that heater hoses were detrimental to the oil passing though.

Next step is to go back and pick up the old engine--planning to pull the head myself. I'm as curious to know what caused the valve to fail. I'll report back when I have it off!
